Peninsular India is a stable region with very less seismic activities, however the region has witnessed several earthquakes. Discuss with examples.

Peninsular India has been a low seismicity region due to its old focus structure and compact landmasses.

Features:

• Volcanic rock origin – Deccan traps.
• Stable landmarks and rift structures, e.g. Narmada rift.
• Low earthquake vulnerability.
• Occasional crust faults, e.g. Bhima fault.

Emergence of seismicity:

• Occurrence of intense earthquakes.
• Rising landslide frequency.
• Rock falls and land slump.
• Mild tremors in Deccan.

Reasons:

• Dam-induced seismicity.
• Unsustainable infrastructure.
• River flow changes.
• Burden of hill tourism.

India must integrate Sendai framework in its disaster planning.
